Issues in upgrading from gcc 2.96 to 3.2.1

["Ajay Bansal" <Ajay_Bansal at infosys dot com>]

Hi All

I have asked a few questions since yesterday. It turns out that almost
all of them in some way related to gcc upgradation from 2.96 to 3.2.1.

Does somebody has a comprehensive list for the same? Os some location?
Or did has somebody faced these issues before???

By the time somebody gives me a list, I have run into another issue
which is as follows


***********************
Test_read.cpp

#include <iostream>
#include <fstream>
#include <string>

 #include <sys/types.h>
       #include <sys/stat.h>
       #include <fcntl.h>

using namespace std;

int main(){
        fstream iostrm;

        iostrm.open("cintest.in", ios::out | ios::trunc, 0644);


   return 0;
}


******************

On compilation with gcc 3.2.1, I get the following error


test_read.cpp: In function `int main()':
test_read.cpp:14: no matching function for call to
`std::basic_fstream<char, 
   std::char_traits<char> >::open(const char[11], std::_Ios_Openmode,
int)'
/usr/local/include/c++/3.2.1/fstream:545: candidates are: void 
   std::basic_fstream<_CharT, _Traits>::open(const char*,
std::_Ios_Openmode = 
   (std::ios_base::in | std::ios_base::out)) [with _CharT = char,
_Traits = 
   std::char_traits<char>]


Do I simply need to change the open call to 

iostrm.open("cintest.in", ios::out | ios::trunc)

And it'll give the required results????
